Fei Qian squatted on the ground and pulled it one by one with wooden sticks, just like a rich man calculating how much food he had left at home.
The first step is that mining technology is not a big problem. It is not yet at the point of deep well excavation, and surface mining is relatively easy. There is no problem with coming out of iron ore. The water grinder is available very early; the second step is to mix lime powder, which is also no problem. When the amount is too high and the amount is small, it will be adjusted according to the condition of the molten iron. The third step is to remove carbon from pig iron to form crude steel ingots. This includes steel stir-frying technology, hydraulic wind discharge, and even over-frying, and steel filling technology. At this stage, it is enough; the fourth step is to forge steel to further remove various impurities, increase the strength and hardness of steel, and then trim the steel ingots into various required equipment. In other words, the biggest problem is that it occurs in this link, and most of the labor is consumed here...
Add water calcining equipment!
First, we will move out the manpower consumption of the rough slaughter first. As for the detailed slaughter, let’s see if there is any progress in the future. In the Han Dynasty, there were water cone trucks and water drains. The operating principles of these equipment were actually similar, but no one used it in the wrought iron industry for the time being, so it only needs to be slightly improved, and the problem is not too big.
But this wire drawing process...
It's really hard to do, and there's no clue at all.
Huang Yueying walked over quietly with a food box, squatted aside with Fei Qian, blinking her big eyes at the things that Fei Qian was smearing and smearing on the ground.
"What are you going to do when you are young?" Huang Yueying squatted beside Fei Qian, supported her elbow on her knees, held her chin, and said in a low voice.
Fei Qian frowned and said, "Turn, or pulling..."
Huang Yueying blinked, murmured and repeated, and then said, "Brush, what thread to draw?"
"How can iron wire be simpler?" Fei Qian drew several molds on the ground, but found that these molds seemed to require higher technology to be able to perform them, so he was very confused, as if he had reached a dead end.
To do wire drawing, you must have tools, and this tool requires higher technical support. You need to develop these basic technologies, including lathes, and in turn, require more cutting-edge materials. It is simply an endless circle that can never be avoided.
Huang Yueying didn't understand what Fei Qian was thinking, but it did not hinder her mood of wanting to help Fei Qian, so she tilted her head and thought for a while, then suddenly stood up and ran away.
Fei Qian didn't care about Huang Yueying's movements at all. He is now mainly worried about how to add to the simple mechanical processes of the Han Dynasty. Many of the techniques and methods he knew from later generations were not implemented in the Han Dynasty for the time being, and this is the most troublesome problem.
I knew what to do, but I just couldn't do it. The conditions were insufficient. I saw the technology tree, but I couldn't point it out. This feeling of depression made Fei Qian almost go crazy.
Huang Yueying ran back again. Behind Huang Yueying, a middle-aged craftsman, holding a large vine box, came to Fei Qian's approaching.
"This is..." Fei Qian was a little confused.
Huang Yueying's breath did not stop, so she urged the middle-aged craftsmen to give a demonstration as soon as possible.
The middle-aged craftsman smiled foolishly, first gave a gift to Fei, and then sat on the ground without saying anything, put the vine box aside, then opened it, took out some small hammers, small clips, some iron sheets, and even a small stove and other things...
The middle-aged craftsman skillfully raised the charcoal fire in the small stove, then took a small cauldron and put it on the fire, took out a small piece of silver and then started to burn it. Although the melting point of the silver was not too high, it still burned for a while. Fortunately, the silver block was not big, and under constant heating, it gradually began to melt.
The middle-aged craftsman took a few iron sheets, and there seemed to be some grooves on the iron sheets, and then poured the melted silver liquid in the crucible onto these iron sheets.
The silver liquid left the fire source and cooled down quickly, forming slender silver rod-shaped forms on the iron trough...
"Well..." Fei Qian pinched the fine fluffy beard on his chin, and understood Huang Yueying's intention a little, so he began to think about it in his heart.
The middle-aged craftsman took out a small hammer without stopping his hand. While the silver was not completely cold, he beat it carefully again, obviously to make the silver rod more even. Then, when the silver rod cooled to a certain level, he took out one of them and took another thick iron plate. There seemed to be many small eyes on the iron plate...
This is...
Brushed board!
Fei Qian's mind was like he was knocked by something, yes, wire drawing board! This most primitive hand-drawn mold was an important tool for making gold-thread jade clothes in the Han Dynasty!
Otherwise, how could such thin silver and gold wire be knocked out one by one?
Sure enough, the middle-aged craftsman knocked the silver rod a little bit, then put it on the wire drawing board, and used a small plier to pull it up bit by bit, and then changed to a smaller round hole. After this three or two times, a thin silver rod was originally a circle of silver wires...
Fei Qian squatted in front of the middle-aged craftsman and picked up the circle of tiny silver wires...
Yes, why do I always think about getting it done in one step?
Separate the wire drawing steps. First, use molds to make thin iron rods. There is no problem. Then, use wire drawing boards, borrow water conservancy transmission, and return to pull the iron rods into wire bit by bit. Then, after being thin to a certain level, you can even use a simple device such as a pulley roller to further refine them...
Of course, there are some problems in it. For example, the melting point of iron is higher than that of gold and silver, and there is no material with a higher melting point and a harder shape than iron to act as a wire drawing board. However, this is not a big problem. Heating and cooling were originally a compulsory course for blacksmiths. I won’t talk about heating. Coking coal is enough to provide enough heat. If cooling is really not possible, use the cooling method of computers in later generations. There is no particularly big problem whether it is air cooling or water cooling.
This is how many things are. When you have no idea, you don’t know how to deal with them. However, after you have a way, you only need to deal with the difficulties that will arise around this way, and you have the hope of achieving your goals.
Fei Qian finally laughed, stood up, bowed to the middle-aged craftsman, thanked him, then turned to Huang Yueying and said, "Thank you too..."
Huang Yueying was a little happy, and a little embarrassed. She twisted her fingers, suddenly remembered something, blurted out: "Oh, it's broken, the soup is cold now..."
